NASA states that: "Remarkable new details of Pluto's largest moon Charon are revealed in this image from New Horizons' Long Range Reconnaissance Imager (LORRI), taken late on July 13, 2015 from a distance of 289,000 miles (466,000 kilometers)."

Here is my processed cropped image of Pluto's largest moon Charon:

The red circle depicts a possible structure at the 8 o'clock position. The structure has a triangular/pyramidal shape that faces upward to the northeast. There appear to be 2 possible structures/buildings located at the 1 o'clock position in the red circle. These structures/artifacts are rectangular in shape. On the left side of the image straight across from the triangular structure are additional possible structures/artifacts of a tubular shape with one long tubular/rectangular structure that intersects at right angles with 2 other tubular/rectangular structures.

The blue circle depicts a large rectangular structure at the 5 o'clock position that appears to have 4 walls and the top of the structure appears to have either caved in or been destroyed or blown away. There appears to be a possible structure/building located at the 1 0'clock position in the blue circle. This structure/building appears to have openings/windows on both the top/roof, right side, and front of the structure/building.

Charon in Enhanced Color NASA's New Horizons captured this high-resolution enhanced color view of Charon just before closest approach on July 14, 2015. The image combines blue, red and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera (MVIC); the colors are processed to best highlight the variation of surface properties across Charon. Charon’s color palette is not as diverse as Pluto’s; most striking is the reddish north (top) polar region, informally named Mordor Macula. Charon is 754 miles (1,214 kilometers) across; this image resolves details as small as 1.8 miles (2.9 kilometers).Credits: NASA/JHUAPL/SwRI

At half the diameter of Pluto, Charon is the largest satellite relative to its planet in the solar system. Many New Horizons scientists expected Charon to be a monotonous, crater-battered world; instead, they’re finding a landscape covered with mountains, canyons, landslides, surface-color variations and more.

“We thought the probability of seeing such interesting features on this satellite of a world at the far edge of our solar system was low,” said Ross Beyer, an affiliate of the New Horizons Geology, Geophysics and Imaging (GGI) team from the SETI Institute and NASA Ames Research Center in Mountain View, California, “but I couldn't be more delighted with what we see."
